OWC 128GB DDR4 2933 CL21 4Rx4 288-pin 1.2V ECC LRDIMM memory upgrade

SKU CH-CZWJ-F5311

A 128GB DDR4 2933 ECC LRDIMM module for HP ProLiant DL560 Gen10, DL580 Gen10, DX360 Gen10, DX380 Gen10 and DX560 Gen10 servers

  • Capacity128GB
  • Type288-Pin DDR4 ECC LRDIMM
  • SpeedDDR4 2933 (PC4 23400)
  • CAS LatencyCL21
  • Voltage1.2V
  • ECCYes

Capacity 128GB

  • 128 GB capacity expands server memory for large workloads
  • DDR4 2933 MHz speed delivers high data throughput for demanding applications
  • ECC load-reduced design detects and corrects errors to protect data integrity
  • 2 V operation reduces power draw in dense memory configurations
  • Compatible with HP ProLiant DL560, DL580, DX360, DX380 and DX560 Gen10 servers

Server-grade capacity

This 128GB DDR4 ECC load-reduced DIMM is built for HP ProLiant DL560 Gen10, DL580 Gen10, DX360 Gen10, DX380 Gen10 and DX560 Gen10 servers. It targets administrators who need maximum memory density in a single module for virtualisation or large datasets.

Build integration

The module requires a 288-pin DDR4 slot that supports load-reduced ECC memory and cannot be mixed with unbuffered or registered DIMMs. It operates at 1.2V and fits the qualified ProLiant platforms without additional configuration.

Capacity and headroom

A single stick delivers 128GB at 2933 MT/s with CL21 latency and is backward compatible with 2133, 2400 and 2666 MT/s bus speeds. Systems limited to lower-density modules or unbuffered memory cannot use this upgrade.

Questions about this item

Will a single 128GB 4Rx4 LRDIMM run at the rated 2933MHz CL21 under continuous server workloads?

The module is specified at DDR4 2933 (PC4-23400) CL21 and will operate at that speed and latency when the host platform supports it.

How much heat and power does the 1.2V load-reduced DIMM generate during all-day operation?

At 1.2V the LRDIMM draws less power and produces less heat than higher-voltage registered DIMMs, and it has no heat spreader, relying on chassis airflow for cooling.

Which HP ProLiant Gen10 servers must I already own for this 288-pin DDR4 ECC LRDIMM to work?

It is validated for HP ProLiant DL560 Gen10, DL580 Gen10, DX360 Gen10, DX380 Gen10 and DX560 Gen10 systems.
